Psychoactive drug use is not just a phenomenon of the 20th
century; many different types of drug have been used throughout
recorded history. In this chapter we will outline the main classes of
psychoactive drug. We are able to do this in a single chapter
because, despite there being thousands of different drugs, they can
be classified in a few main groups (Table 1.1). The crucial role of

The second chapter case study by Rosso et al. presents a medical survey that tests
professional drivers for the presence of various psychoactive substances. Positives
were identified by using a commercially available immunoassay rapid kit test which
indicates consumption of psychoactive drugs. This is of interest and important since
the dependence on drugs may pose a risk to drivers in their profession affecting their
reaction time and driving judgment. This is one of the first and important
contributions to the literature in this area.
Case studies for existing risks in the first section include drug use in Italian
professional delivery truck drivers and using look-back risk assessment for syringe reuse
in Canada. The first chapter by Oraby et al. describes the occurrence of syringe reuse
reported in a Canadian health care setting on approximately 1,400 patients in the
province of Alberta. Multiple syringe re-use events may act as a vector to transmit
both RNA and DNA viruses.
Caffeine, a nonselective adenosine A1 and A2A receptor antagonist, is the most widely used psychoactive substance in the world. Evidence demonstrates that caffeine and selective adenosine A2A antagonists interact with the neuronal systems involved in drug reinforcement, locomotor sensitization, and therapeutic effect in Parkinson's disease (PD). Evidence also indicates that low doses of caffeine and a selective adenosine A2A antagonist SCH58261 elicit locomotor stimulation whereas high doses of these drugs exert locomotor...
The third was conceived under the influence of a number of powerful smart drugs and psychoactives. He'd sort of run out of biological steam by the fourth kid, and just slapped an egg and some sperm together in vitro, letting some tech implant them.
